Here is the environment for the setup Ubuntu 12.04 (32 bit) R (Ubuntu comes with 2.14.1, so updated to 3.0.2) Installed the latest rmr2 and rhdfs from here<https://github.com/RevolutionAnalytics/RHadoop/wiki/Downloads>and the corresponding dependencies Hadoop 1.2.1 Now I am trying to run a simple MR program as Sys.setenv(HADOOP_HOME="/home/training/Installations/hadoop-1.2.1") Sys.setenv(HADOOP_CMD="/home/training/Installations/hadoop-1.2.1/bin/hadoop") library(rmr2) libr...

...son de lo mejorcito para paralelizar, Spark como comentó Carlos tiene implementado SVM lineal pero hoy por hoy no lo podrás ejecutar desde R (si desde python). Otras opciones que te recomiendo es probar con otros algoritmos, mira por ejemplo h2o (http://h2o.ai/) (2) Con esto te vale perfectamente RHADOOP y cualquier svm implementado en R ya que cada svm es 'pequeño' solo que tienes que hacer muchos (3) Lo mismo que (2) puedes te vale con RHADOOP y hacer `predict` en paralelo.

Buenos días, Tengo instalado un cluster en una máquina virtual y he instalado R y Rstudio (sobre Ubuntu server 14.04 64 bits ) .

...ion is : *what would be the best combination of technologies/CRAN package to address those two problems ?* My idea for the moment is : - Using Rserver in combination with a Ruby client. Alternatively, I am thinking about writing myself the server in Java and using existing R/Java bindings. - Using RHadoop to handle jobs on big datasets. I saw RevoDeployR is a great tool but is not open source, isn't it ?

Hola, Puedes poner un RStudio en Amazon, poner "caret" y a correr.... No sé si tendrás suficiente con lo que te pueda ofrecer Amazon para tu problema... creo que sí... ;-)....
